Martin, thank you. Sure, the -if- command is all on one line. Thanks
for the globals suggestion. So for example I could do
*** begin code ***
program define mycmd
gettoken subcmd 0: 0
if "`subcmd'"=="reg" | "`subcmd'"=="areg" | "`subcmd'"=="xtreg"{
global command `"`subcmd'"'
mycmd_ols `0'
}
... ...
end
program define mycmd_ols
di " $command"
end
...
*** end code ***
or how is the use of global within -gettoken- to be understood? I tried
***
gettoken (global) subcmd 0: 0
***
but it did not work.
Thanks,
AC
